Subject [jira] Commented: (SOLR-1877) Investigate unclosed Reader in IndexBasedSpellCheck
Date Sat, 15 May 2010 14:21:42 GMT


Yonik Seeley commented on SOLR-1877:

I really don't know the spellcheck framework, but I did just take a quick look...

It seems like we have multiple readers to worry about:
1)  the reader possibly obtained from solr
2) any reader opened explicitly by IndexBasedSpellChecker
3) the reader the lucene spellchecker has

This patch looks like it would try to close a solr-obtained reader too.  It would also be
nice to close all of the readers when the core is closed, and not just on a reload too.

The whole spellchecker  thing looks a bit fragile actually... what's stopping the obtained
reader from being closed by solr?
We may need to expand the review to the whole solr spellchecker to figure out how to address
these problems correctly.
